Using parameter p0180 you can define the number of command data sets (2, 3 or 4).
Table 7- 52 Selecting the number of command data sets
Parameter Description
p0010 = 15 Drive commissioning: Data sets
p0180 Drive data sets (DDS) number(factory setting: 1)
p0010 = 0 Drive commissioning: Ready
Table 7- 53 Parameters for switching the drive data sets:
Parameter Description
p0820 Drive data set selection DDS bit 0
p0821 Drive data set selection DDS bit 1
p0826 Motor changeover, motor number
r0051 Displaying the number of the DDS that is currently effective
For an overview of all the parameters that belong to the drive data sets and can be switched,
see the Parameter Manual.
Note
You can only switch over the motor data of the drive data sets in the "ready for operation"
state with the motor switched-off. The switchover time is approx. 50 ms.
If you do not switch over the motor data together with the drive data sets (i.e. same motor
number in p0826), then the drive data sets can also be switched over in operation.
Table 7- 54 Parameters for copying the drive data sets
Parameter Description
p0819[0] Source drive data set
p0819[1] Target drive data set
p0819[2] = 1 Start copy operation
